To all whom it may concem:

Be it known that I, ALIHONS RAPPE- NnoKnn, engineer, a subject of theGerman Emperor, residing at 102 Donanst-rasse, Bremen, Germany, haveinvented certain new and useful Improvements in Developing Apparatus forTWriting-Telegraphs and the Like; and I do hereby declare the followingt-o'be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to an electrically driven developing apparatusfor films,

chiefly for those writing-telegraphs which effect the transmission ofcommunications by an clecho-photographic process. The apparatus,however, can be used also for any other development apparatus. Theworking of the receiving apparatus of the first mentionedwritingtelcgraphs hitherto has not been con'lplctcly automatic, as thereceivers always had to he attended by some one who cut oil, at asuitable point the posed portion of the film which was to be developed,from the remaining stock of film. This was a drawback, for the receivingap paratus must be able to take text and pictures received and finishthem photographically, even when nobody is present. To that end thedevice for cutting oil' the film is provided, according to thisinvmtion, with a gear which can be switched iii or out from thetransmitting station; the gear in question being preferably conne ted tothe feed device for the film and of he construction hereinafterdescribed. Figure 1 shows diagrammatically the side elevation of thephotographing and developing apparatus. Fig. 2 shows separately and onan enlarged scale. the automatic shears used for cutting the film. Fig.3 shows the corresponding connection diagram.

The upper portion of the camera a is occupied by the drum Z) with thefilm 0, while in the bottom portion of the camera are arranged baths fordeveloping and the like. The film 0 passes from the drum 1) first overthe guide roller (1. thence bctwecn 'the guide rollers c and c. in orderto pass-=1 er the guide roller 7 where it turns and passes around thedipping roller 9 0t theceveloping bath to the guide roller 71, dippingrollers of the fixing bath and between the guide rollers 7c, is out ofthe casing. On the rollers situated in the interior of the casing aremounted toothed wheels of about the same diameter arranged outside andmarked with the same reference letters. The driving of the device ispreferably efiected from the electric motor Z which, by means of thespindle m, rotates the Worm Wheel a connected by the toothed Wheel 9 tothe toothed Wheels f andh. On the same spindle asthe toothed wheel 9, ismounted a smaller toothed wheel 0 for driving the spindle of the camdisk 9 on which is also mounted the toothed wheel 1;. The various ratesof transmission and speed of rotation are calculated in such a mannerthat the cam disk 1 makes exactly one revolution during the completeoperation of the device.

To the casing of the camera a is secured by means of bolts 1", the levers which slides by me-ans of a block t, on the cam disk 1 and is pressedagainst the latter by springs. The free end of the lover s is connected,preferably through a spring, to a slide u on which is mounted. free torotate on a pin, the coupling wheel '0 which, on the slide be ingraised, couples the wheels f and e. The slide 'u-is adjustable in aguide of the casing a which can be closed so that/no light can get in,and is controlled by a spring 10 which pulls it down (Fig. 2). The slideit engages by means of an eye m a pin of the blade 2 of the shears. thisblade being pivoted about a pin 2. The other blade 3 of the said shearsis arranged in a fixed manner above the film. A spring to engaging withthe pivoted blade y, tends to close the shears.

.The working of the apparatus is as follows: As soon as the motor Z hasreceived current from the telegraphic transmitter apparatus, it startswith the spindle m the worm wheel 72. the toothed wheel 0 and the camdisk q (first a little idle movement). The worm wheel 11. drives alsothe toothed Wheels f 7!- and also and 71;, it but at first without anyaction, as the film c and the rollers c, holding the same, remainunaffected. The coupling wheel 1) ot the slide a is, at the moment,still at such a distance from the wheels 7 and c that the teeth are notyet in engagement. Only when the lover s is slowly raised by the camdisk acting on the block 6 the slide a will also be raised and bring thecoupling wheel o into engagement with the wheels 7' and 6. At that"moment the roller 9 will pull the 1 film and move it downward, so thatas into an almost vertical means cotipe much film as required by thetelegram taken,

will be carried under the fixed shearing.

blade 1 to the baths, in the meantime, the cam disk 3 has made almost acomplete revolution, the lever s has been raised still further, andturned the pivoted blade ;1 oi the shears, which was previouslyhorizontal, position. At the moment when the block 25 springs away fromthe cam at the cam disk 1 the slide a springs back into the initialposition into which it is pulled by the spring to (Fig. 2), the looseblade y of the shears springing then into the closed-position of theshears and cutting the film On the cam disk q is mounted an electriccontact device which, shortly before the end of the operative movement,breaks the circuit of the motor Z, so that the gear stands still. Thesmall additional. movement of the motor (due to momentum) can beutilized for closing the contact again at the cam Wheel 9. At thatmoment, owing to special devices, the motor does not at once get currentagain, but remains standing still, until. it again receives current fromthe transmitter station, which takes place only when a new section offilm is ready for developing and cutting oil. This is effected asfollows: When at the transmitter station (Fig. 3), by a suitableoperation of the writing pencil, orby any other means the contact 5 isclosed within the line circuit 6 supplied with current by the source 7,the .relay 3 of the receiver station will attract the armatures 2 andthusclose the circuit of the source of current 4 of the receiverstation, which will there upon drive the motor Z. The motor starts thegear of the lilm and its cut-tinged device, so that thecam disk Qrotates. The spring contact Z is normally closed and not atiected by thecamdisk 9. Shortly before the end of its one revolution, the like of thecam disk strikes a spring projection of the contact Z, and opens it fora moment, so that the relay 3 releases the armaturcs 2 and breaks themotor circuit. The motor continues, however, to rotate a little, so thatthe cam disk completes its revolution, and the contact Z, being releasedby the stop pin, is again close l. The motor Z remains neverthelesswithout current. as the arnnitures 2 are lying free, and the linecircuit is at rest. Obviously instead of the electric motor Z aclockwork driving device could be employed released from the transmitter station. i
